Notification Area change with latest Fast Ring build question

I updated a W10 OS and I'm seeing something i've never seen before.
The Notification Area shows left and right arrows to scroll, and a large blank area in the right corner.
This is a W10 Insider Preview fast ring OS, updated to the latest offered.
It's a bare metal install, not a VM, version info is in the screen print.

Has anyone else seen these arrows with the latest Fast Ring OS ?

I like to see all icons in the Notification Area, all the time.
I've checked my settings, and i think they are right for me, and have always worked before this "fast ring version update".

Screen print 1 shows what i see with the latest W10 Fast Ring version.

Screen print 2 shows what i see with the latest W10 RTM version,
this is what i like and has always worked for me in W7, W8.x, and W10 - until my latest fast ring update.

See if Edwin's answer about "Input Indicator" is applicable to your problem................

Changing the Input Indicator did not work for me.

Why don't you go back to that thread and ask Edwin ?
He might have answer for you.

Hey David,

This is a known bug in build 14271 for the taskbar notification area. If you have more than seven icons in the taskbar notification area, it will disrupt the layout of the notification area and show white scroll bars with arrows. Turning off the “always show all icons in the notification area” setting helps fix this for now as long as you do not set to show 7 or more icons.

Thank you, Brink.

It is DavidE asking the question.

How come my Insider Preview 14271 does not have this problem ?

Thank you, Brink.

I suppose that if you already have the above turned off OR don't have many notification area icons showing it wont have this issue.

Thanks davidhk and Brink for the help.
I'll turn off Always show all icons in the notification areauntil MS fixes this.

Glad we could help.
